Point S is on line segment RT. Given RS = 4x – 10, ST = 2x – 10, and
RT = 4x – 4, determine the numerical length of RS.
Answer:
The numerical length of RS is 22 units
Step-by-step explanation:
∵ Point S is on the line segment RT
→ That means S divide RT into two parts RS and ST
∴ RS + ST = RT
∵ RS = 4x - 10
∵ ST = 2x - 10
∵ RT = 4x - 4
→ Substitute them in the statement above
∴ 4x - 10 + 2x - 10 = 4x - 4
→ Add the like terms in the left side
∴ (4x + 2x) + (-10 + -10) = 4x - 4
∴ 6x + (-20) = 4x - 4
∴ 6x - 20 = 4x - 4
→ Add 20 to both sides
∴ 6x -20 + 20 = 4x - 4 + 20
∴ 6x = 4x + 16
→ Subtract 4x from both sides
∴ 6x - 4x = 4x - 4x + 16
∴ 2x = 16
→ Divide both sides by 2 to find x
∴ [tex]\frac{2x}{2}=\frac{16}{2}[/tex]
∴ x = 8
→ Substitute the value of x in Rs to find its length
∵ RS = 4(8) - 10
∴ RS = 32 - 10
∴ RS = 22 units
The numerical length of RS is 22 units
Answer:
RS=4

In a list of five consecutive odd integers, the sum of the first and double the last is 139. What is the largest sum?
Answer: 49
Step-by-step explanation:
From your question, I think you mean the largest number. The answer is given below.
Let the five consecutive odd numbers be:
a, a+2, a+4, a+6 and a+8.
Thee sum of the first and double the last is 139. This can be written as:
a + 2(a+8) = 139
a + 2a + 16 = 139
3a + 16 = 139
3a = 139 - 16
3a = 123
a = 123/3
a = 41
The first number = 41
The largest number = a+8 = 41 + 8 = 49.

the price of a videotape is $13.20 after a 40% discount. Whats the original price?
Answer:
$22
Step-by-step explanation:
So if a videotape was on a 40% discount, then the person who is buying it pays 60% of the original price (100 - 40 = 60)
call "x" the original price, then set up a proportion to explain the relationship
13.2/x = 60/100
simplify
13.2/x = 3/5
solve using cross products
13.2/x = 3/5
13.2 * 5 = 3 * x
66 = 3x
22=x

consider the equation below. which are NOT power functions? select all that apply
A. f(x)=2^4√ x
B. f(x)=pi/x
C. f(x)=2*3^x
D. f(x)=√2/^3 √ x
E. f(x)=2(x-3)^1/2
F. f(x)=x^2+2x-6
Answer and Step-by-step explanation: Power Functions are of the form:
[tex]f(x)=ax^{b}[/tex]
where a is scaling factor, which means, it moves the values of [tex]x^{b}[/tex] up or down;
and b is exponent or power, which determines the rate of growth or decay of the function.
The difference between exponential and power functions, is that in power functions, a variable base is elevated to a fixed exponent.
For that reason, Equations:
A. [tex]f(x)=2^{4\sqrt{x} }[/tex]
B. [tex]f(x)=\frac{\pi}{x}[/tex]
C. [tex]f(x)=2.3^{x}[/tex]
D. [tex]f(x)=2^{3\sqrt{x} }[/tex]
are NOT power functions.

What is the slope of the line that passes through the points (-3, 3) and (-3, 13) ? Write your answer in simplest form
Answer: The entered points belong to a vertical line. There is no slope.
Equation: x = -3.
This is what i think..
The slope is the ratio of the rise to the run of a line. It is also called the rate of change or gradient. Therefore, the slope of the line is 0
Slope = Rise / Run
Rise = y2 - y1 = (13 - 3) = 10
Run = x2 - x1 = (-3 - (-3)) = (-3 + 3) = 0
Slope = Rise / Run = 10 / 0 = 0
Therefore, the slope of the line is 0

Sanjai had $175 in his bank account before he got paid this week
His current balance is $287. How much did he get paid?
Answer:
$112
Step-by-step explanation:
To find the amount he got paid, subtract the current amount from the initial amount
so
287 - 175
= 112
Hey there!☺
[tex]Answer:\boxed{\$112}[/tex]
[tex]Explanation:[/tex]
Sanjai had $175 in his bank account before he got paid this week. And now his total is $287. Represent x as how many he got after he paid. So that means you do $175 + x = $287.
[tex]175+x=287[/tex]
We have to find x and see how much money he got paid to get 287 in his balance.
[tex]287-175=112[/tex]
x is equal to 112. Let's see if $112 makes x true.
[tex]175+112=287[/tex]
That makes x true which means he got paid $112.
Hope this helps!☺
1. Cuando se compra pintura ,por la general , se venden galones(un galón equivale a 3.7354L)y se reparten en botes de 1/4L o otra fracción de litro. a) Si compro dos galones y debes repartirlos en botes de 1/4L¿comó sabes cuántos botes pueden llenar?
Answer:
Se requiere 30 botes de 0.25 litros para dos galones de pintura.
Step-by-step explanation:
Sabemos que un galón equivale a 3.7354 litros, para estimar en cuantos botes de 0.25 litros se puede distribuir dos galones, empleamos la siguiente expresión:
[tex]n = \frac{V_{total}}{V_{bote}}[/tex]
Donde:
[tex]V_{bote}[/tex] - Volumen del bote, expresado en litros.
[tex]V_{total}[/tex] - Volumen total, expresado en litros.
[tex]n[/tex] - Cantidad de botes a llenar, adimensional.
Si sabemos que [tex]V_{bote} = 0.25\,L[/tex] y [tex]V_{total} = 2\,gal[/tex], entonces:
[tex]n = \frac{(2\,gal)\cdot \left(3.7354\,\frac{L}{gal} \right)}{0.25\,L}[/tex]
[tex]n = 29.883[/tex]
Puesto que la cantidad de botes es representada por un número entero,la cantidad requerida se redondea por exceso al entero más cercano. En consecuencia, se requiere 30 botes de 0.25 litros para dos galones de pintura.
Which regular polygons could be used to make regular and semi-regular tessellations? Check all that apply.
- equilateral triangle
- square
- regular pentagon
- regular hexagon
- regular octagon
- regular nonagon
- regular dodecagon
Answer:
A. equilateral triangle
B. square
D. regular hexagon
E. regular octagon
G. regular dodecagon
Step-by-step explanation:
The regular polygons could be used to make regular and semi-regular tessellations are equilateral triangle, square and regular hexagon. Therefore, the correct answers are A, B and D.
A regular tessellation is tessellation made up by using only one type of regular polygon. These are made up of completely congruent regular polygons all that connecting vertex to vertex.
Regular polygons have congruent straight sides. When we slide or rotate a regular polygon, the side of the original figure and the side of its translation will match.
Equilateral triangles, squares and regular hexagons are the only regular polygons that tessellate. Therefore, there are only three regular tessellations.
Therefore, the correct answers are A, B and D.

The five-number summary of the distribution of scores on the final exam in Psych 001 last
semester was min =18 Q = 39 Med = 62 Q = 76 Max = 100. A total of 416 students
took the exam. About how many students had scores above
39? (A) 104
(B) 208
(C) 312
(D) 400
First quartile of the distribution is, Q = 39.
i.e 75% of students have scored more than 39.
So, total number of students scored more than 39 are :
[tex]n=\dfrac{416\times 75}{100}\\\\n=312[/tex]
Therefore, number of students scored higher than 39 are 312.
Hence, this is the required solution.
Solve for x; 6x + c = k
Answer:
x= (k - c) / 6
Step-by-step explanation:
6x + c = k
6x = k - c
x = (k - c) / 6
Answer: [tex]x=\frac{k}{6} - \frac{c}{6}[/tex]
Step-by-step explanation:
6x + c = k To solve for x first subtract c from both sides
-c -c
6x =k - c Now divide both side by 6.
x= k/6 - c/6
